Hey

I've woken up on the last day of a trip with those awful precursors to a head cold. Sniffly nose, raised glands, that headache that you know is going to result in sneezes.

It's less than 24 hours to my return flight (premium cabin, >8 hours in the air). I already have my boarding pass.

If I wanted to postpone this flight a few days, what are my options? Will BA charge me through the nose for the changes?
